Wolverine star, Hugh Jackman, called into Ryan Seacrest’s radio show all a-twitter about his Twitter web page.

The actor told Seacrest he was using the site to challenge fans logging onto his profile. The deal? “I’ve decided to make a pledge to give $100,000 to whoever Twitters to me their charity in 140 characters that really resonated with me,” Jackman says. So, one lucky charity is going to get 100 grand just for a quick explanation of why the group deserves the money.

Jackman goes on to tell Seacrest that he sees Twitter as an opportunity to raise awareness and to “give air space to charities” adding “I’ve just be blown away by what people are putting online.”
